Abstract: According to the summary of research results in recent years,combining with numerical simulation and practical experience,the paper emphasizedly analyzed the influencing factors and effect of the filling material’s mechanical properties,the filling wall’s geometric parameter,the roof’s rock structure,the stoping speed and other factors on roadside wall’s stability,the paper draw the conclusions that the high-water rapid hardening materials and the paste filling material have good load-supporting properties,the different of optimal value of the filling wall’s width in different conditions and the construction quality have a great influence on the roadside wall’s stability.
